Mtundu wamphamvu kwambiriwirewound resistorsNthawi zambiri amavotera pamwamba pa 1W, ngakhale mpaka mazana angapo Watts, ndipo angagwiritsidwe ntchito pa kutentha kwambiri yozungulira. Miyezo yokana imatha kuyambira ma ohm angapo mpaka mazana angapo kilohm, ndi kukana kwathunthu kwa ± 5% ndi ± 10%. Zida zamtundu wa wirewound resistor kwa chigoba, mafunde, mapeto otsogolera ndi wosanjikiza wotetezera; wirewound resistor ndi chopinga chokhazikika chopangidwa ndi chilonda chokanirira pa chigoba chotetezera, waya wotsutsa nthawi zambiri amapangidwa ndi nickel-chromium, manganese-copper ndi ma alloys ena, mafupa otetezera nthawi zambiri amakhala aluminiyamu ceramic, encapsulation zipangizo ndi insulating varnish, silikoni, utoto, ceramics, aluminiyamu chipolopolo ndi zina zotero. Zopinga zathu za simenti wamba, ma trapezoidal aluminium casing resistors, ndi ma ripple resistors onse ndi amphamvu kwambiri ma wirewound resistors, okhala ndi zida zosiyanasiyana zotsekera.
Chifukwa chiyani makabati owongolera amafunikira kugwiritsa ntchito ma wirewound resistors amphamvu kwambiri?
Sikoyenera kugwiritsa ntchito mphamvu zapamwambawirewound resistorskwa makabati olamulira, koma ma wirewound resistors apamwamba kwambiri amphamvu ayenera kukwaniritsa zofunikira zawo zowongolera, ngati sizofunika, sizingagwiritsidwe ntchito. Makabati ambiri owongolera safuna ma wirewound resistors amphamvu kwambiri, ndipo omwe amatero ndi osowa. Mwachitsanzo, ambiri wamba wamba galimoto kuyambira makabati ulamuliro safuna mkulu mphamvu wirewound resistors, pamene galimoto pafupipafupi kuyambira makabati kulamulira ayenera mkulu mphamvu wirewound resistors monga resistors ananyema.
Mphamvu zapamwambawirewound resistorskuyambira 5mΩ mpaka 100KΩ. Ma Wirewound resistors amapangidwa ndi waya wa Nichrome kapena waya wamkuwa wa Manganese, waya wa ConocoPower pamachubu a ceramic, zopinga za RX20 zitha kugawidwa m'mitundu iwiri: yokhazikika komanso yosasinthika.
Ubwino wa ma wirewound resistors apamwamba kwambiri: kukana mwatsatanetsatane, phokoso lochepa, lokhazikika komanso lodalirika, kutentha pang'ono, kupirira kutentha kwambiri, kutentha kozungulira 170 ℃ kumatha kugwirabe ntchito bwino.
